Battery life after installing iOS 4.0 on 3GS

I've read a little about loss of battery life on the 3GS after installing 4.0 so I was curious who else is experiencing these problems. Since installing the new software my phone is losing about 8-10% per hour when sitting idle. I am losing a full charge and using the phone less than 30 min. I have done a restore and have made sure aps are closed. I can;t get the phone to stop eating battery life. Any suggestions?? Please!

Bingo.....decided to try a restore factory settings through ITunes and then backed up with the phone settings so I did not lose all my stuff, if this had not worked I would have tried again but then reset as a new phone and start afresh, but thankfully I did not need to. Note you still end up with OS 4.0
After going through the set up and then recharging just once, the battery has performed pretty much as it is has done since initial purchase. In 16 hrs of minimal usage and in standby it has used 30%.
Good luck.
Cheers

HT4623 why am i experiencing short battey life after installing ios 7?

why am i experiencing short battey life with my IPad after installing ios 7 1 ?

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.

At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

What is going on the my battery life, after installing Mavericks, what a drain!!!

What is going on the my battery life, after installing Mavericks, what a drain!!!

You can try resetting the SMC and NVRAM.
http://support.apple.com/kb/ht1379
http://support.apple.com/kb/ht3964
You can also try running the short and/or extended Apple hardware test by holding D button while booting up and then following the instructions.
http://support.apple.com/kb/ht1509
If that doesn't work (seems not extremely likely that it will) you can backup and try reinstalling a fresh OS.
If that still doesn't work maybe the battery is bad. If you don't feel like messing with all that just take it to Apple. They should have a test they can perform.

I Have been getting BAD battery life after the ICS UPDATE !! on the DROID RAZAR MAXX have this happen to any one else ??????

i have been getting really bad battery life after install ICS on my droid razar maxx i can only go 1 day and 3 hours where i used to be able to go 2 day easy have this happen to anyone else can someone tell me how i can make my battery life better??????/ and do i need to let my phone go complete dead before fully chargeing it again ??????
before install the ICS update i had 30 percent of battery life remaining so i pluged it in and let charged for a little bit while it updated my phone and ever thing after it updated i unplug my phone and started playing on my phone to see what ICS was all about but when it got to 15 and said " connect to your changer so i did !!!!! should i haved let my phone going complete dead since i unplug without it fully changer or does it matter ?????????????? if someone could please help me !!!!:)

What was your battery reading right after the update when you unplugged the phone? I have never let my Maxx drain further than 20% battery ever before I charge it. Yesterday after the update I also played more with the phone trying to learn the OS, as did most everyone on this forum. Give it a few days of your normal use before you decide your battery life has decreased. I took my phone off charger today at noon, it was 100%, and now it's 80%, with about 30 min talk time, and mostly standby. that's about normal batt life for me, maybe a little better than before the update. I'm still going to watch it for a few days before I make a conclusion about battery life.

After installing iOS 6 battery life is awful on iPhone 4S

Hello All,
I just want to share a problem I am having with my iphone 4s. After installing iOS 6.0.1 on it, the battery life is very bad, I could probably say unacceptable, after fully charging it, it would not last even 12 hours before the battery runs out and also i have noticed that the battery or back of the phone gets hot, I would say hotter than before I did the upgrade. I am just wondering if anyone could share some thoughts. I hope Apple comes out with a fix to this issue because I have noticed that a lot of people are having this problem.
Thank you

Hmmm...Apple doesn't support downgrading. If true you must have jailbroken your phone rather than properly repair the problem.

Any iPhone 4S users experienced better battery life after upgrading to iOS 7.1?

Hello
I am curious to know if any iPhone 4S users experienced better battery life compared to iOS 7.x.x.? That will be great to know before I upgrade and give up my JB .
Thanks!

Apparently when the issue affects you personally it's impossible to accept that millions and millions of users are not experiencing the same problems or accept that the issue is with your device specifically.
Really, that's quite an assertion. I'm sure you can prove those stats; but my apologies, I forgot that Apple produces flawless product.
I can only report MY SYMPTOMS: iPhone 4S 32M on VZW, upgrade to iOS 7.0 at the end of February (when security flaw was announced), after which my battery life is about 1/2 what it used to be before the upgrade.
Also, as reported above, when I upgraded to iOS 7.0 my phone would lock (in phone mode); had uncommanded reboots; and severely degraded battery life. Two days ago, upgraded to iOS 7.1. Most screen "touch" issues appear resolved; and uncommanded reboots resolved.
Battery life / duration still poor; still charging every 4-5 hours.
Previously with normal use (with no location services) could run a full day, about 8 hours before recharge. Now, same situations, I'm having to recharge after 4-5 hours. Again, no new apps, all apps are current; no different usage.
What's the resolving fix?

Why after installing iOS 7 my iPad started to reboot by itself, my battery lost autonomy and the iPad got slowwwwwwer?

For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

After installing iOS 6 update my ipod touch 5G doesn't work anymore

after installing iOS 6 update my ipod touch 5G doesn't work anymore. Can anybody help me? Please!

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My ipad 2 won't hold a charge after installing ios 7

I use the authentic Apple charger and my ipad 2 won't hold a charge after installing ios 7. What is the fix for this miserable wasteful upgrade that made all of our iPads unusable ! I Shut off location, turned off brightness, shut down and took off apps. WHAT NOW for my iPad ?

Batteries eventually fail, and it sounds like that's happened with your iPad. You'll need to take or send it Apple to get the battery replaced. See:

Wireless driver triggers warm/hot macbook and low battery life after OS 10.8 mountain lion upgrade

Hello frustrated Macbook users.
I have tried to get help on other Apple discussions but no one seems to want to help, they aren't actually reading my posts, or they hate me for some reason.
No matter.
If you have a warm Macbook that has 2.5 hours of battery life where you used to have 4 or more, please do this simple procedure and write the result below.
Turn OFF Airport wireless networking
Perform an SMC reset (Power Manager)
Connect an ethernet cable and use your Macbook normally. (but do NOT turn on wireless networking again)
How is your battery life after doing this?
I have a user over here who reclaimed decent battery performance if he doesn't use his Airport wireless.
I need confirmation.
If so, I may get a USB wireless adapter and see if the battery life stays good.
Bonus points: If you have a Mac compatible USB wireless adapter and got good results by turning off the built-in adapter, want to test it for me and report the results?
Thanks and good luck!

UPDATE:
Problem persists when using Recovery Partition.
Chance sthat it is third party softwae or updates is more or less eliminated.
Update 10.8.3 beta fixed the problem for one lucky early adopter.
Hypothesis: New battery charging algorithms programmed into Mountain Lion OS10.8 triggered problems from design flaws that were NOT an issue for OS 10.7 and before.
Battery replacements were successful where the replacement battery was built within tolerances that did not fail under 10.8's new charging algorithms. Other bateries did not meet those tolerances so you would get spotty results from battery replacements. It worked sometimes, but not always.
OS 10.8.3 may have adjusted these algorithms to be less demanding on the features of the battery that were failing.
Official word from Apple is 'mum'.

Battery drain after installing IOS7 on Iphone 4

Hi
I have recently installed IOS7 on my IPhone 4.
The battery drains really quickly even when I am not doing anything with the phone. I never had these problem before updating.
Suggestions please???
Thanks

I have also noticed what appears to be decreased battery life after the upgrade, though not this bad. Seems many people are noticing problems.
I noticed and changed a couple of settings that seem to have helped.
- first, fully shut off the phone and then turn it back on - i read online this helped some, immediately after the update.
- in mail settings, for the icloud account (I dont use this but it was configured by default) check the sync settings . it defaults to push, which takes more power. you might want to disable push and set to fetch for this and any other accounts you have, for additional power savings
- in settings, location services, scroll to the bottom and tap system services : All of them are defaulted to on. I turned off location-based iads and setting time zone since i dont need those. (I also opted out of the diagnostics and usage as part of the setup, but it was set to on in this screen - i left it on for the time)
- also in settings -- location settings: check the list of apps and verify that only the ones you want, are enabled
These few settings seem to have improved things

Is it normal for iPhone 4S to lose 1% battery life after 2-3 minutes of using?

Is it normal for iPhone 4S to lose 1% battery life after 2-3 minutes of using? So in 2 hours, 24 minutes usage and 15 hours, 17 minutes in standby mode, the battery became 68%...

sounds plausable
also you can't really 100% trust it's batt% batteries are an analog technology the only thing the iphone can judge how much batt is left is by measuing amp amount the batt is producing and then over time estimating how long before it's zore
but anyway Its not wise to not put a battery for charge before bed when it's 12%
if your reason is you think it's good for batteries to be empty before charging then you believe in a myth and in the process damaging the battery in your ios device

HT1414 anyone noticing a decline in battery life after downloading ios7????

anyone noticing a decline in battery life after downloading ios7?

I have an iphone 5. Ios 7 is a disaster for battery life! It used to drain about 1% every two hours, 5% over night roughly (not being used). Now it is draining at double the rate. It drained 10% over night and it isn't even doing a thing. I think something is clocking up usage when it's idle.
Screen brightness is minimal.
Background app updating is restricted to one app which isn't running the majority of the time.
Dynamic wall paper and other stupid stuff is all turned off.
I can't turn off the stupid clock animation. I wonder if working out how that is displayed is the issue???
It shouldn't be draining at 1% per hour when not even being used.
Favourite locations is still switched on.
Is there any benefit in turning off wifi and using 3g data only? I had the issue before that having 3g enabled meant double the battery drain so I only used it when I was out.
Ipad mini seems fine though. Battery life is same as last ios6 ie about 14-16 hours use.
I now have caret running to find out what the rogue thing is. The majority of the time few apps are running at all.
My general average usage is 12-15% per day if lightly used and 25-45% if it is moderately used. Now the phone is draining at 25-33% a day when lightly used!
Beats me why an ipad mini which is advertised at up to 10 hours on wifi nearly doubles that and the iphone which is advertised at the same rarely reaches it. I usually get 8 hours of active use if I'm lucky. Now it's more like 5-6 which is hopeless.
